What Is a Personal Protective Buddha?

A念持仏 (nenjubutsu) is a small Buddha image kept close at hand throughout life, offered daily prayers and devotion. Unlike a larger enshrined protective Buddha, it was often small enough to carry — taken to battle, on journeys, and kept beside the pillow at night. For a warrior, it was as essential as armor.

Yakuoji Temple in Kanazawa Ward, Yokohama, is a quiet Shingon Omuro temple that preserves the nenjubutsu of Minamoto no Noriyori (c.1150–1193) and continues to hold the annual Mikawa-ki memorial ceremony on August 24 each year.

Minamoto no Noriyori: A General in His Brother’s Shadow

Noriyori was a half-brother of Minamoto no Yoritomo who played a decisive role in the defeat of the Taira clan at the Battle of Dan-no-ura in 1185. Despite his military achievements, he fell under suspicion of disloyalty and was exiled to Izu in 1193, where he disappeared from history. His title as Governor of Mikawa (Mikawa no Kami) gave the memorial ceremony its name: Mikawa-ki.

Yakuoji’s dedication to preserving his memory through an annual ceremony speaks to a deep current in Japanese Buddhist culture — the commitment to honoring those whose lives were cut short by the turbulence of power.

The Two-World Mandala: Womb Realm and Diamond Realm

Yakuoji holds a silk painted Ryokai Mandala designated as a Yokohama City Cultural Property, dating to the Heian period. This remarkable work visualizes the esoteric Buddhist cosmos through the lens of Shingon teaching.

FAQ

Why did Minamoto no Noriyori disappear from history?

In 1193, Noriyori was accused of disloyalty after remarks he made were reported to Yoritomo as evidence of treasonous ambition. He was confined at Shuzenji Temple in Izu and never heard from again. Whether he was killed or died by his own hand remains unclear.

What is the Shingon Omuro sect?

The Shingon Omuro sect is a branch of Shingon Buddhism based at Ninnaji Temple in Kyoto, founded in 886 by Emperor Uda. It preserves the esoteric teachings of Kukai (Kobo Daishi) and is known for its elaborate ritual traditions, including goma fire ceremonies and mandala veneration.
